Three issues surfaced when running the MV smoke tests against westin-v19:
1. account_bank_statement_line has no `date` column in V19 — `date` is a
related field flowing through move_id -> account_move.date. The MV
now JOINs account_move and selects am.date.
2. is_reconciled is nullable; replace `= FALSE` with `IS NOT TRUE` so
nulls (genuinely unreconciled lines that haven't had the compute run
yet) are still included.
3. _refresh() now flushes the ORM cache (env.flush_all()) before the
REFRESH so computed-stored fields like is_reconciled are written to
the DB before the materialization snapshot reads them. Previously the
reconcile-then-refresh path saw the pre-reconcile column value.
4. _trigger_mv_refresh() (suggestion create/write hook) now uses
concurrently=False because Postgres forbids
REFRESH MATERIALIZED VIEW CONCURRENTLY inside a transaction block,
and Odoo's per-request cursor is always inside one. The cron path
(Task 25) will open an autocommit cursor for CONCURRENTLY refreshes.
5. Tests dropped the env.cr.commit() pattern: Postgres always shows a
transaction its own writes, so a non-CONCURRENTLY refresh in the
same txn picks up freshly-inserted rows. Cleaner + works inside
TransactionCase, which forbids cr.commit().
Verified: 4 new MV tests pass, 0 failures across 118 logical tests
(178 with parametrized property-based runs) of fusion_accounting_bank_rec
on westin-v19.

CREATE MATERIALIZED VIEW fusion_unreconciled_bank_line_mv pre-computes
the data the kanban widget needs (top suggestion, confidence band,
attachment count, partner reconcile hint) so that listing 50-100 lines
is one indexed query instead of N+1.
Refresh strategy:
- Triggered on fusion.reconcile.suggestion create/write (best-effort,
never poisons the originating transaction)
- Cron (every 5 min) — added in Task 25
The MV is created in the model's init() (Odoo calls this on
install/upgrade). The SQL DDL is idempotent
(CREATE MATERIALIZED VIEW IF NOT EXISTS / CREATE INDEX IF NOT EXISTS)
and includes a UNIQUE(id) index so REFRESH MATERIALIZED VIEW
CONCURRENTLY is supported. _refresh() falls back to a blocking refresh
on the first call after creation.
